The correct answer is a prompt injection attack, and the best mitigation is input validation combined with context sanitization. This attack exploits the chatbot’s inability to distinguish between legitimate user instructions and malicious commands embedded in the input, allowing an attacker to override the system’s original directives and extract sensitive data. On the CompTIA AI+ AI0-001 exam, this question tests your understanding of adversarial input attacks specific to large language models, often appearing in the “AI Security” domain. A common trap is confusing prompt injection with model inversion or membership inference—remember that prompt injection targets the input layer, not the model’s training data or outputs. For a quick memory tip, think “inject, then reject”: the attacker injects a malicious prompt, and you reject it by sanitizing inputs and isolating the chatbot’s context from its system instructions.
AI0-001 AI Security, Ethics and Governance Practice Question
This AI0-001 practice question tests your understanding of ai security, ethics and governance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a penetration test, a security engineer discovers that an AI-powered chatbot can be tricked into revealing sensitive customer data by using specially crafted prompts. What type of attack is this, and what is the best mitigation?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Prompt injection attack; implement input validation and context sanitization
Option D is correct: the attack is a prompt injection, and input validation (sanitization) is a primary defense. Option A is wrong because model inversion is different. Option B is wrong because this is not a membership inference attack. Option C is wrong because differential privacy is for training, not for prompt-level attacks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Prompt injection attack; implement input validation and context sanitization
Why this is correct
Prompt injection exploits the model via crafted inputs; validation prevents it.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Model inversion attack; apply differential privacy during training
Why it's wrong here
Model inversion reconstructs training data, not prompt-based leaks.
✗
Data poisoning attack; implement strict access controls
Why it's wrong here
Poisoning corrupts training data, not runtime prompts.
✗
Membership inference attack; add noise to model outputs
Why it's wrong here
Membership inference determines if a record was used in training.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the AI0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
